Patented Nov. 25, 1930 UNITED" STATES PATENT OFFICE LOUISIANA, Assrenon or our: HUNDRED -PER GMT TO CARL W. GIBSON, 0F PARISH OF ORLEANS, LOUISIANA GAS BURNER Application filed November 22, 1928. Serial No. 321,120.

This invention relates to a gas burner, and particularly to a construction adapted for use in gas furnaces wherein the combustible mixture is ignited at a refractory inlet bafiie.

With this type of burner it is of particular importance to avoid a stratification of the gas and air which results in an incomplete mixture at the point of ignition materially reducing the effective heat of the flame.

Further, unless the air admixture is effected in a highly heated zone, the expansion and regenerative effects upon the constituents are lost. Again, if'the air be admitted to the burner through an opening common to all the baflle ports there is no concentration or draft in alinement with such ports which will effectively produce a mixture with the gas discharged under pressure at the burner.

To avoid these objections and render the burner more efficient, I have formed the burner with 3. central head and lateral branches having burner tips disposed centrally of the ports of the refractory baflle and provided with orifices arranged to proj ect the gas jet into contact with all walls of the port which results in a rebounding movement of the gas causing the same to be broken up and thoroughly mixed with the admitted air. By pro ucing the mixture entirely within the ports of the baflle I utilize the high temperaturethereof to expand or regenerate both the air and gas and as the air completely surrounds the jet the most desirable admixture is secured.

I have also combined with the burner a damper plate having air apertures alined with the ports ofthe baflie and controlled by a door formed with inclined projections cooperating with said apertures, so that the inclined faces direct the air into the apertures and produce a direct draft into the mixing ports. I

The invention has for an object to provide a novel and improved gas burner combined with a refractory bafile having a plurality of ports and comprising a head having lateral branches with discharge means disposed substantially centrally of the ports and formed with jet orifices arranged to proburner baflie and a cooperating register door provided with projections opposite said plate havlng apertures alined with the ports of a v with inclined walls to seat in the apertures thereof.

Other and further objects and advantages of the invention will be hereinafter set forth I and the novel features thereof defined by the'appended claims.

numerals of reference refer to like parts in the several figures of the drawings.

. In the application of the invention shown 1n Figs. 1 to 6, the numeral 10 designates a fllrnaceor chamber to be heated which may be of any desired construction. The wall 11 thereof is provided with the usual opening within which is disposed a refractory baflie 12 carried by a metal frame 13 having a front wall 14. The baflie in this form of the inventlon comprises oppositely arranged diagonal partitions 15 forming a plurality of staggered rectangularports 16.

Cooperating with this baflleis a burner head 17 having at each side a series'of lateral horizontal branches 17 formed with ppositely inclined front walls 18 to prevent resistance to the inflowing air. The face of these branches next the baflle is provided with burner tips 19 which may be integralbr threaded therein, as shown in Fig. 6. The tips are formed with pyramidal faces 20 having jet orifices 21 disposed to direct a gas jet into contact with the several walls bf the ports. These tips are arranged substantially centrally of the baflle ports so that they are surrounded by the inflowing air which is thus brought into intimate contact with the This plate 26 is formed with apertures 28.

alined with the ports 16 of the baflie,.and a register door 29 is slidingly mounted upon guides 30 and provided with projections 31 having inclined walls 32 to seat in said apertures when the air inlet is closed. When partially open these inclined walls direct the air into the apertures and assist in producing a direct draft through the baflie ports, as 1ndicated by dotted lines in Fig. 1. The guides 30 may be mounted in the boss 33 on the plate 26 and provided with stops 34 at their free ends to limit the movement of the door away from the damper plate. y

The modifiedform of the inventionshown by Figs. 7 and 8 simplifies and economizes the manufacture of the burner, and the baffie 35 therein is provided with rectangular orts 36, but they are not staggered as in ig. 4. The burner head 37 has lateral branches 38 formed with integral pyramidal tips 38 disposed at the center of the ports and provided with orifices 39 to direct a gas jet into contact with all the walls of the port The mounting of the burner and the construction of the air inlet damper may be similar to that before described. I

In the further modification shown by Figs. 9 and 10 the baflie 40 has a vertical partition 41 and horizontal partitions 42 forming elongated ports 43. The burner head 44 has branches 45 formed with orifices 46 disposed to project a jet of gas into direct contact with the walls of the port.

The disposition of the burner orifices to project a gas jet into contact with the wall of the bafile port causes the admixture with the airto occur within a highly heated zone and the mixture to be forced into the angles of the ports which results in a uniform feed and the reflex movement of the mixture through the battle port. The register door permits an accurate control of the air admitted to the burner and its direction to'efiect a draft toward the burner and port.

The specific construction of the several parts has been shown and described, but the invention is not confined thereto, as changes and alteration may be made without departing from the spirit of the invention as recited in the following claims. I

What I claim, is:

1. In a gas burner, a refractory baflie formed with a plurality of angular ports, a burner head having lateral branches provided with gas discharge means located substantially centrally within the ports and having angularly disposed orificed faces to project a gas jet into contact with the walls of said ports, and means for supplying air to said discharge means.

2. In a gas burner, a refractory baflle formed with a plurality of angular ports, a burner head having lateral branches, and pyramidal discharge tips located substantially centrally of the portsand having orifices to project a jet into contact with the walls thereof.

3. In a gas burner, a refractory baflle formed with a plurality of ports, and a burner having gas discharge tips located substantially centrally of the ports directly adjacent the inlet thereto, said discharge tips being provided with opposite walls having orifices to pro'ect a gas jet angularly into contact with t e walls of the ports.

4. In a gas burner, a refractory baflle formed with a plurality of rectangular ports, a central burner head having opposite lateral branches, and pyramidal discharge tips located' substantially centrally of the ports and havingorifices to project jets into contact, with all walls of the ports.

5. In a gas burner, a refractory baflle having angular ports, a frame surrounding said baflle and having a front wall, a burner head having extended ends and discharge branches with jets substantially centrall of said ports and having angular faces or' ced opposite all walls of the ports, and straps embracing the extended ends of said head and secured to said front wall.

6. In a gas burner, a refractory bafile having an angular port, and aburner provided with a pyramidal discharge jet with orificed walls correspondin to those of the port and disposed at an ang e thereto.

7. In a gas burner, the combination with a refractory bafile having ports and a gas feed cooperating therewith, of a damper plate at the inlet end of the ports having air apertures, and a sliding door having its face next said plate provided with parallel elongated projections formed with inclined walls to cooperate withsaid apertures.

8. In a gas burner, a refractory baflle having oppositelyinclined partitions to form a m series of staggered angular ports, a burner head having branches provided with discharge jets extended into said ports and formed with oppositely inclined faces direct-' ed toward the angular walls of the ports, and damper means for directing a draft of air into alin'ement with said ports.

In testimony whereof I aifix my signature.
